Frequently asked questions

What is the RTC4933 rotor arm used for?

The RTC4933 rotor arm sits inside the ignition distributor cap and distributes the high-voltage spark to each plug in the correct firing order. It's the Ducellier-type arm for 4-cylinder petrol engines, fitted to the Land Rover Defender 1983-2006 and Series 2 and 3.

How do I know if I need the Ducellier rotor arm and not the Lucas type?

Check which distributor is fitted first. The RTC4933 only suits Ducellier distributors; Lucas distributors use a different arm. The rotor shape and cap fixings usually differ between the two makes, so confirm your distributor before ordering to avoid the wrong ignition part.

What are the signs a rotor arm needs replacing?

Common signs are misfires, rough running, hard starting, or a no-start once the arm cracks or carbon-tracks internally. Rotor arms are a typical ignition service item on Ducellier-equipped 4-cylinder petrol engines, and they're usually replaced alongside the distributor cap for a reliable spark.
